When the original image pickup device 1 is activated, as shown in FIG. 3, first, the first buffer memory 6 is cleared in step S1, and then the second buffer memory 7 is cleared in step S2. Then, in step S3, a re-display counter for counting the number of document information accumulated in the second buffer memory 7 is initialized to 0. Next, in step S4, a redisplay pointer indicating a variable indicating which page data is being transferred to the display memory 8 among the plurality of page data stored in the second buffer memory 7 is initialized to 0. . For example,
When the value of the redisplay pointer is 0, this value indicates that the page data was read last, and the value is 1
Each time it increases, it indicates that the page data is older.
In the following step S5, the display memory 8 is initialized. In the initialization of the display memory 8, the connection between the device 1 and the display device 15 and the operation of the device 1 can be confirmed instead of the data of all black or all white, and the screen size and the image quality can be adjusted. Possible data is read from the ROM 12 and initialized with the data. Alternatively, the data of the display memory 8 is initialized by the calculation of the CPU 11. Then, in step S6, a document discharge process is performed.

Next, as shown in FIG. 4, step S7
In step S11, it is determined whether or not any one of new display, rotation display, mirror image inversion display, redisplay, and thumbnail display is instructed by the operation designating switch 14.
Here, when none of the above is instructed,
In step S12, it is determined whether there is a document on the document tray 18 based on the output of the document set detector 19. If there is no document on the document tray 18, the above step S
Returning to step 7, if there is a document on the document tray 18, it is determined in step S13 whether or not there is a free space in the first buffer memory 6. If there is no free space in the first buffer memory 6, the process returns to step S7. If there is free space in the first buffer memory 6, the original is read in step S14. Details of this document reading process will be described later. Then, the process returns to step S7.

When the new display is instructed in step S7, the new display is performed in step S7 '.
The procedure returns to step S7. When the rotation display is instructed in step S8, the rotation display is performed in step S8 ', and the process returns to step S7. Step S above
When the mirror image reverse display is instructed in step 9, step S

Details of the new display, rotation display, mirror image inversion display, redisplay, and thumbnail display will be described later.

In the present embodiment, when the original set detector 19 detects the original bundle 17 accumulated on the original tray 18 (step S12), the first buffer memory 6 has a free space. Whether or not (step S
According to 13), the reading of the original is immediately started,
Instead of this, for example, when a new display is instructed, continuous reading of the documents stored on the document tray 18 may be started.

Next, the document reading in step S14 will be described with reference to FIG. FIG. 5 is a flowchart showing the procedure for reading the original document in step S14 of FIG.

In reading a document, as shown in FIG. 5, first, in step S21, the R, G, and B light sources built in the linear image sensor 2 are turned on. Here, while reading one line, the light sources of R, G, and B are switched on and turned on. Then, in step S22, the motor is rotated to drive the paper feed roller 21 and the separation roller 20. As a result, one document 16 is fed from the document stack 17 accumulated on the document tray 18.

Next, in step S23, the document position detector 3 waits for the document 16 to be detected. When the document 16 is detected by the document position detector 3, in step S24, the document 16 is continuously fed until it reaches the sub-scanning main roller 22 with reference to the timing when the document 16 is detected, and in step S25, The rotation direction of the motor is switched to the sub-scanning direction at the timing when the document 16 reaches the main roller 22. That is, the paper feed roller 21
The drive of the separation roller 20 is stopped, and the drive of the sub-scanning main roller 22 and the paper discharge roller 23 is started. Then, in step S26, the conveyance of the document 16 in the sub-scanning direction is continued.

Next, in step S27, the manuscript 1
At the timing when 6 reaches the original readable position (position on the white plate 24), A / A from the linear image sensor 2
Data transfer to the first buffer memory 6 is started via the D converter 5, and in the subsequent step S28, the transfer of data for one original is completed. When the transfer of the data for one original is completed, the data transfer is completed in step S29.

Next, in step S30, the R, G, and B light sources of the linear image sensor 2 are turned off, and in the following step S31, the document discharge process is performed and the motor is stopped. Then, in step S32, it is determined whether the read image data is monochrome. Here, when the read image data is monochrome, step S
At 34, a monochrome flag is set for this image data, and the process proceeds to the next step. On the other hand, when the read image data is not monochrome, step S34 is skipped and the process proceeds to the next step.

Next, the reading operation in reading the original will be described in detail.

When the original 16 reaches the readable position on the white plate 24, the R, G, and B primary color lights emitted from the respective light sources are generated in the case of a non-transparent original according to the image information of the original 16. Is the surface of the original 16 and, in the case of a transparent original, the original 16
And the plate surface of the white plate 24, and the reflected light is read by the linear image sensor 2 as R, G, B data. The CPU 11 detects the timing at which the document 16 deviates from the readable position on the white plate 24 by converting it from the timing when the trailing edge of the document 16 passes the document position detector 3, and recognizes that the reading of the document 16 is completed. To do. The R, G, and B image information of the original 16 read by the linear image sensor 2 is converted into digital data by the A / D converter 5, and image processing such as gradation conversion and edge enhancement is performed as necessary. After that, it is stored in the first buffer memory 6.

Next, the document discharge in step S31 will be described with reference to FIG. FIG. 6 is a flow chart showing the document discharge processing procedure in step S31 of FIG.

In document ejection, as shown in FIG. 6, first in step S51, the motor is rotated in the sub-scanning direction,
The sub-scanning main roller 22 and the paper discharge roller 23 are driven. Then, in step S52, the process waits until the document 16 passes through the document position detector 3 based on the output of the document position detector 3. When the document 16 passes through the document position detector 3, the motor is driven until the document 16 is reliably disengaged from the paper discharge roller 23 in step S53. here,
The document 16 is conveyed by the distance until the trailing edge of the document 16 passes the document position detector 3 and the trailing edge of the document 16 comes off the paper discharge roller 23. Then, in step S54, the document 16 is surely ejected from the discharge roller 2
Stop the motor at the timing deviating from 3.

Next, the new display in step S7 '(FIG. 4) will be described with reference to FIG. FIG. 7 shows FIG.
5 is a flowchart showing a procedure of a new display in step S7 ′ of FIG.

In the new display, as shown in FIG. 7, first, in step S41, it is determined whether or not data is stored in the first buffer memory 6, and when there is data in the first buffer memory 6, In step S44, the data in the first buffer memory 6 is set in the second buffer memory 7. On the other hand, when there is no data in the first buffer memory 6, it is determined in step S42 whether or not there is a document on the document tray 18. If there is a document on the document tray 18, the document is read in step S43. By reading this document, new data is stored in the first buffer memory 6. Then, in step S44, the data newly stored in the first buffer memory 6 by the reading of the original document is transferred to the second buffer memory 7
Set to.

If it is determined in step S42 that there is no document on the document tray 18, the instruction to display a new document is ignored.

Next, the data set in the second buffer memory 7 in step S44 will be described with reference to FIG. FIG. 8 is a flow chart showing the processing procedure of the data set in the second buffer memory 7 in step S44 of FIG.

In the data set to the second buffer memory 7, as shown in FIG. 8, first, in step S61, it is determined whether or not the second buffer memory 7 has a free space, and there is no free space ( If the memory is full), the oldest data in the second buffer memory 7 is deleted from the second buffer memory 7 in step S68, and the redisplay counter is decremented in step S69. Then, the process returns to step S61. This is because, since the data in the second buffer memory 7 is compressed, it is unclear whether even if one data is deleted, another one data can be stored.

If it is determined in step S61 that the second buffer memory 7 has a free space, step S62 is performed.
At 0, the redisplay pointer is set to 0, and in the subsequent step S63, the rotation counter is set to 0. The value of the rotation counter indicates how many times the image in the display memory 8 is rotated with respect to the original data in the second buffer memory 7. Here, when the value of the rotation counter is n, the value indicates that it is rotated by an angle of π / 2 (90 °) × n, and n takes an integer value from 0 to 3. Therefore, when 0 is set in the rotation counter, it is confirmed that the image data in the display memory 8 becomes the newest data in the second buffer memory 7, and the rotation is not performed and the image data has the same orientation as the original data. Will be shown.

Next, in step S64, the oldest data in the first buffer memory 6 is subjected to image processing such as resolution conversion, gradation conversion, edge enhancement, etc., if necessary, and the data after this image processing is performed. Is transferred to the display memory 8. At this time, when the output mode is set to the monochrome mode, that is, when the monochrome flag is set, the above data is converted into gray scale data and transferred to the display memory 8. The grayscale data may be data of R, G, and B single colors, or may be data obtained by calculating luminance data. Here, the transfer of the data of the first buffer memory 6 instead of the second buffer memory 7 to the display memory 8 is for preventing the expansion processing of the extra data.

Then, in step S65, the oldest data in the first buffer memory 6 is compressed and transferred to the empty area of the second buffer memory 7, and the subsequent step S65.
At 66, the redisplay counter is incremented. Then, in step S67, the oldest data in the first buffer memory 6 is deleted from the first buffer memory 6.

The data transferred to the display memory 8 is converted into a video signal by the video signal generator 9, and this video signal is sequentially output to the display device 15 for display. Here, the video signal generated by the video signal generator 9 is an analog RGB signal used in a personal computer or the like, but instead of this, it can be directly connected to the display device 15, and the display device 15 can be connected in real time. A signal that can notify the change of the data in the display memory 8 and can be reflected in the display content may be used. As such a signal, for example, DF
P (Digital Flat Panel Standard) and IEEE139
There are digital signals as specified in 4.

In this embodiment, as shown in FIG. 4, an image displayed on the display device 15 is rotated and displayed,
It is possible to perform image operations such as mirror image inversion display and redisplay. First, rotation display, which is one of image operations, will be described with reference to FIG. FIG. 9 shows step S of FIG.
It is a flow chart which shows the processing procedure of rotation display of 8 '.

In the rotating display, as shown in FIG. 9, first, in step S71, it is determined whether or not the value of the redisplay counter is zero. Here, when the value of the redisplay counter is 0, this value indicates that there is no data in the second buffer memory 7 and the original read data is not displayed yet. Ignore the instructions.
If the value of the redisplay counter is not 0, step S7
In 2, the calculation of modulo 4 (MOD4) is performed after incrementing the rotation counter to obtain the value of the rotation counter of the angle to be rotated this time. By performing this modulo operation, the instruction of 2π (360 °) can be returned to the instruction of 0 (0 °). Subsequently, in step S73, of the data stored in the second buffer memory 7, the data indicated by the redisplay pointer is expanded.

Next, in step S75, it is determined whether or not the value of the rotation counter is 0. When the value of the rotation counter is 0, the expanded data is transferred to the display memory 8 in step S80. .

On the other hand, when the value of the rotation counter is not 0, the value of the rotation counter is determined in step S76. Here, when the value of the rotation counter is 1, in step S77, the rotation processing is performed on the expanded data so as to rotate the image displayed on the display device 15 by π / 2 (90 °). . When the value of the rotation counter is 2, in step S78, rotation processing is performed on the expanded data so as to rotate the image displayed on the display device 15 by π (180 °). When the value of the rotation counter is 3, step S
At 79, the image displayed on the display device 15 is changed to 3
Rotation processing is performed on the expanded data so as to rotate by π / 2 (270 °). In addition, the above step S7
At 7, S78 and S79, image processing such as resolution conversion, gradation conversion, edge enhancement, etc. is performed on the above data as needed. Then, in step S80, the data rotated in any of steps S77, S78, and S79 is transferred to the display memory 8.

Next, the mirror image inversion display in step S9 'will be described with reference to FIG. FIG. 10 shows FIG.
8 is a flowchart showing a processing procedure of mirror image inversion display in step S9 ′ of FIG.

In the mirror image inversion display, as shown in FIG.
First, in step S91, the value of the redisplay counter is 0.
Or not. Here, if the value of the redisplay counter is 0, this value indicates that there is no data in the second buffer memory 7 and the original read data is not yet displayed, so that the mirror image reverse display is performed. Ignore the instructions.

On the other hand, if it is determined in step S91 that the value of the redisplay counter is not 0, step S91
In 92, the data indicated by the redisplay pointer is read from the second buffer memory 7, and in the following step S93,
The read data is expanded. Then, step S9
In 4, the above-decompressed data is subjected to mirror image inversion conversion,
Further, image processing such as resolution conversion, gradation conversion, edge enhancement, etc. is performed as necessary. Next, in step S95, the mirror-inverted data is transferred to the display memory 8.

Next, the redisplay in step S10 'will be described with reference to FIG. FIG. 11 is a flow chart showing the processing procedure of re-display in step S10 ′ of FIG.

In the re-display, as shown in FIG. 11, first, in step S81, it is determined whether or not the value of the re-display counter is 1 or less. Here, when the value of the redisplay counter is 1 or less, there is no data in the second buffer memory 7 or there is only one value, and the original reading data is not displayed yet. Either it does not exist, or it indicates that only the data which is currently transferred to the display memory 8 and is being displayed is stored in the second buffer memory 7. Therefore, the redisplay instruction is ignored.

On the other hand, if the value of the redisplay counter is not 1 or less, that is, 2 or more, step S82.
In step 1, after incrementing the redisplay pointer, a modulo operation is performed with the value of the redisplay counter to obtain the value of the rotation counter for the data in the second buffer memory 7 to be displayed this time. By performing this modulo operation, it is possible to set the redisplay order of the oldest data next to the newest data.
